Sensor-equipped “smart homes” improve long-term care options for senior citizens, allowing them to life safely in their homes and maintain their independence. These homes recognize and analyze behavior patterns (eating, sleeping, and movement) and report signs of illness or cognitive degeneration to caretakers and physicians. Compared to the high cost of other long-term care options, sensor-enabled smart homes are affordable. For the rising population of senior citizens across the globe, sensors improve their quality of life while reducing the total cost of their long-term care.
